Security checks for vulnerabilities and agentic risk
Overview
This skill is a disclosed X/Twitter post retrieval helper using Gecho Bridge and a Chrome extension, with no bundled code or hidden persistence found.
Install only if you are comfortable letting Gecho Bridge and its Chrome extension access the X content visible in your logged-in browser session. The artifact says it will not collect passwords, payment information, post content, solve captchas, or operate outside the official Gecho MCP workflow.
Vulnerability Patterns
- Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
- Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
- Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
- Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
- Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
